specification, the unwind header in clang was updated with necessary
declarations.  However, when building with an older compiler, we would not have
the necessary declarations.  This would result in a build failure.  Provide a
supplementary header to ensure that the necessary declarations are present for
the build of the C unwinding personality.

Note that this is NOT an ABI break.  It merely is a compile time failure due to

equivalently.  This header should permit building with clang[<3.9] as well as

7 years ago[CUDA] Driver changes to support CUDA compilation on MacOS.
Justin Lebar [Fri, 18 Nov 2016 00:41:22 +0000 (00:41 +0000)]
[CUDA] Driver changes to support CUDA compilation on MacOS.

Summary:
Compiling CUDA device code requires us to know the host toolchain,
because CUDA device-side compiles pull in e.g. host headers.

When we only supported Linux compilation, this worked because
CudaToolChain, which is responsible for device-side CUDA compilation,
inherited from the Linux toolchain.  But in order to support MacOS,
CudaToolChain needs to take a HostToolChain pointer.

Because a CUDA toolchain now requires a host TC, we no longer will
create a CUDA toolchain from Driver::getToolChain -- you have to go
through CreateOffloadingDeviceToolChains.  I am *pretty* sure this is
correct, and that previously any attempt to create a CUDA toolchain
through getToolChain() would eventually have resulted in us throwing
"error: unsupported use of NVPTX for host compilation".

In any case hacking getToolChain to create a CUDA+host toolchain would
be wrong, because a Driver can be reused for multiple compilations,
potentially with different host TCs, and getToolChain will cache the
result, causing us to potentially use a stale host TC.

So that's the main change in this patch.

In addition, we have to pull CudaInstallationDetector out of Generic_GCC
and into a top-level class.  It's now used by the Generic_GCC and MachO
toolchains.

7 years agoAllow use define symbols to override linker defined ones.

Allow use define symbols to override linker defined ones.

I hit an internal linker script that was defining _DYNAMIC instead of
letting the linker do it. It turns out that both bfd and gold allow
that.

This is pretty easy to implement, just make the linker defined symbol
weak. This should have no impact in the case where there is no user
defined symbol: The visibility is hidden, which causes the output to
still be local.
